GRAIN-SCOURER.

Specification of Letters Patent.

Patented July a, role.

Application filed October 8, 1913. Serial No, 794,103,

To all whom it may concern:

Be it known that I, CHANDOS ROY DIMM, a citizen of the United States,residing at Muncy, in the county of Lycoming and State of Pennsylvania,have invented certain new and useful Improvements in Grain-Scourers; andI hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,which form part of this specification.

This invention relates to grain scouring machines of that class in whicha rotating scouring cylinder is arranged within a cylindrical casing,and the object of the present invention is to provide such machines withnovel means for regulating and controlling the amount of scouring actionupon the grain passing through such machine.

In the accompanying drawings I have illustrated one practical embodimentof the invention as applied to a machine of the horizontal type; and tomore readily explain the invention I will describe such embodiment indetail, so that those familiar with the art will be able to understandthe invention and adapt it to scouring machines of various types.

The essential features of the invention and the novel construction ofthe parts for which protection is desired are set forth in the claimsfollowing such description.

In said drawings-Figure l is a horizontal transverse section through ascouring machine equipped with my novel regulator. Fig. 2 is an enlargedtransverse sectional view of the regulator section of the casingdetached. Fig. 3 is an enlarged face view of the regulator valve. Fig. 4is an enlarged view of part of the regulator casing section. Fig. 5 masection on line 55, Fig; 3.

The scouring casing is usually cylindrical in cross section, and may beof any suitable construction. In the example shown it is. formed of anannular series of longitudinal vertical sections 1 which are providedwith ears 1 at their meeting-edges by which they are united together bymeans of tie-bolts 1". One of the ordinary sections of this casing isreplaced by a section 4: which contains the securing regulator thatembodies the present invention and will be more fully explainedhereafter. The scouring casing, in the example shown, is supported inany suitable manner, and in a preferably horizontal position, in a frame7 of suitable construction.

Within the scouring casing there is a scouring cylinder, which may becomposed of disks 2 mounted on a shaft 2* and provided with peripherallugs or ribs 2 to which are bolted the securing blades or brushes 3,that may be of any desired construction, and are usually arrangedtangential to the disk-s so that when the cylinder is rotated saidblades will have a tendency to throw the gra n forclbly outward againstthe inner wall of the casing. The general construction and operation ofthe casing and cylinder are well known and need no further descriptionherein.

The regulator section 4 above referred to .may be provided with lugs etwhich are wall of the casing; and, said plate 5 is pro I vided at itsrear Side, near its upper edge,

with lugs .5 that are perforated for the passage of a hinge-rod 5 whichrod engages corresponding lugs or openings 4? in the ends of the section4; near the upper edge thereof, so that the regulating plate 5 can beswung by rocking said shaf so as to move the lower end or edge of theplate to or from the scouring cylinder. The inward swing of theregulating plate may be limited by suitable means, a stop-lug 5 beingshown on the upper edge of the plate adapted to engage a correspondingabutment l on the adjacent side of the section 4;; see Fig, 2.

The shaft 5 extends outside of the machine and may be provided with anysuitable means whereby the shaft can be rocked and locked so as toadjust and 1. .1.d the regulating plate ,5 in any desired position. Asshown in the drawings a slotted sector 6 is secured to the outer end Ofthe shaft 5, and the slot in the sector is engagedby. a bolt 6 fastenedto the frame, and provided with a wing-nut 6" by which the, sector canbe clamped to hold the regulating plate in any desired position. 4

A filler 4 may be placed in the section 4, adjacent the hinged edge ofthe regulating plate, to prevent the grain from passing over the hingededge of this plate into the chamzisfthe peculiar formation of the innersur- .ratcheted,as at 5, the serrations or ratchets ber in section 4:.Any grain that might pass into this chamber behind the regulating platecan escape back into the casing at the lower edge of the section l.

One of the novel features of the invention face of said regulatingplate. As shown, it is provided on its inner'face wlth trans- .verseribs 5, which extend circumferentlally "of the scouringcasing, and arepreferably inclined at an angle to the perpendicular, this inclinationbeing, from top to bottom, toward the feed end of the machine. Thesidesof these ribs 5 adjacent the feed end of the machine are preferablyserrated or pointing downwardly. Preferably the in v.ner face of theregulating plate is also longitudinally serrated or'ratcheted betweenthe ;ribs as at 5 such serrations or ratchets 5 also pointingdownwardly. Said plate also preferably has at its end, adjacent the feedend of the machine, a head flange 5 which is preferably slightly deeperthan the ribs 5 land will prevent the grain which may bedirectedforwardly by the first rib 5 from flying too far back toward thefeed.

. Operation: When the machine is to be i operated the regulating valveis adjusted so that its inner surface practically forms part of theinner scouring wall of the casing, and

when the scouring cylinder is rotated the grain is thrown outwardly bythe blades against the casing, and owing to the inclination of theblades the grain is gradually directed rearwardly toward the dischargeend of the machine. Some grain requires more [scouring than others andwhere an increased scouring. efiect is desired the regulator 5 isadjusted farther inward so that the ribs 5 more fully'engage the grainand owing to their inclination such ribs will retard the. passage ofgrain and direct it toward 1 tirely out of the path of the grain, asindicated in dotted lines in Fig. 1, if only very I light scouring isrequired; or by adjusting the regulating-plate fully inward the greatestscouring effect can be produced because in such position the retainingribs 5 have full effect uponthe grain and most effectively re tard thepassage thereof through the machine. jThe ratcheted surfaces of the ribsand of the inner face of the regulating-plate enhance the. scouringeffect of the regulating plate upon the grain.

When theregulating plate 5 is moved inward or toward the revolvingcylinder the area or space between the'corrugated sur-' face of suchplate and the cylinder is reduced so that the grain is brought intocloser contact with the heaters on the cylinder and is therefore scouredmuch harder or more thoroughly between the scouring cylinder heaters andthe longitudinal ribs on the regulating plate; and when the regulatingplate is moved outwardly the scouring action is lessened. Thus byproperly adjusting the regulating plate the grain may be scoured to anydesired extent.

What I claim is:

1. In a grain scouring machine, the combination of a casing, anadjustable regulating plate extending longitudinally of the casing andprovided on its inner face with 'ribs adapted to direct the grain towardthe feed end of the machine.
